Just wondering how long ago Ghetsis found him. He's definitely older than Ash (height difference), so I can only guess he's around Cilan's age. Is Cilan's age ever mentioned either?
It wasn't given exactly, but he is older than 15, as seen here. Pokemon Wiki
Well it might have been mentioned but I don't remember it. There's some speculation on it, but personally I'd guess his between 14 and 15. Anyway everyone's older than Ash his been 10 for the past decade or so XD Also apparently Cilan is 15
